javascript - 表单提交字段为空白。使用 Javascript 隐藏和显示字段

Question

我的问题是，当我填写此表格并提交时。当我在 origin_city_search div 上时，它总是将 Origin_Radius 提交为空

我对这个问题的假设是，由于我有两个名称相同的相同字段(Origin_Radius)，因此它总是采用最后一个字段的值。在下面的形式中，它是 origin_zip_search DIV 中的形式...半径形式有效...只是不是 origin_city_search DIV 中的形式。

任何关于如何让它在每个 div 上提交 Origin_Radius 的指示都会很棒。

为每个字段使用不同的名称，不能有 2 个具有相同名称的字段，请使用“origin_radius_cs”和“origin_radius_zip”之类的名称
